BOTTLE FILLING AND SEALING MACHINE.

Application filed December 14, 1921. Serial No. 522,207.

To all whom t may concern:

Be it known that I, AMos CALLEsoN, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Bottle Filling and Sealing Machines, of which the following is a specification.

This invention relates to machines for illing and sealing bottles or similar containers, and it consists in certain improvements whereby the filling and sealing of bottles one after another may be made t0 take place very rapidly and with the least amount of loss of pressure, as in filling with charged liquids, and whereby theconstruction of the various parts is rendered simple and eflicient and the work of the attendant serving the machine is reduced to simply watching the operations. It will simplify understanding of the improved machine to preface the present description thereof with the remark that the various operations occur while the bottles are moved in a procession at a constant level and that the forming of a sealed space around each bottle head at the time of lling and before sealing the effecting of a certain interlock between parts concerned in the sealing or closure-aiixing operation, and the introduction of the closure into position over the bottle head preliminary to the atiixing or sealing are accomplished by resort to iuid pressure, the second and third of these operations being in the present adaptation actually accomplished by utilizing the pressure `of the air which in filling is discharged from the bottle.

On the base a is arranged an arched pedestal bv for the hopper c for the closures. The back part of the base is depressed and affords a step-bearing d and also a socket e for a fixed upright shaft f around which re- Volves on the step-bearing an upright including the followin parts: a cylindrical basal member g to w ich is afiixed a turret h; a nut f'. journaled in and concentrically with member g,- and a superstructure comprising three members rigidly secured together and forming practically a unit, to wit, the threaded sleeve y' having its threading engaged with nut z', the cylinder lc surmounting the sleeve, and the head l surmounting said cylinder, said superstructure being adapted to be adjusted vertically in the basal 'member by turning the nut which at m is geared with a suitable manually turnable spindle n journaled in the basal member. Parts y', and Z form a casing for a barrel cam o which does not rotate but which may move up or down with said superstructure on adjusting the latter, the same being splined at p to the (non-rotary) shaft f. The turret has aiiixed thereon or forming a part thereof an upstanding ring (7 which is recessed peripherally at regular intervals to receive the bottles, which stand upon the turret. la* and k* are telescoped portions of 7i. and c, splined together as shown so as to insure member If: rotating with the rest of the upright.

The top of the base forms a table r over which the bottles slide in passing to and from the turret, it being flush with the top of the turret and cut away (Fig. 2) to receive the same. Above the table are arranged two minor turrets 7L', 7L, each peripherally recessed to receive the bottles, one functioning to deliver bottles to and the other from the main turret l1.. All three turrets are geared together, as indicated at s s in Fig. 2, and they are rotated (i. e., the aforesaid upright, including turret 7L turning bodily) at constant speed in any desired way, as by the worm-and-worm-wheel connection t between a suitably driven drive shaft u and the depending shaft v of one of the minor turrets. The direction of rotation is shown by arrows, Fig. 2; suitable guides w may be provided to direct each empty bottle into a recess of turret l1. and retain it there until said turret has deposited the bottle on turret h and in a recess thereof, and to shunt each lled bottle oif turret L, retain it in a recess of turret la" for a time and then cause its discharge from the machine. The recesses in the several turrets are spaced so as to synchronize and form bottle sockets as those of the main and either minor turret come into registry with each other.

A disk-like table a: is fixed on head Z and its periphery is received in a recess y formed in the hopper c so that, though the table rotates, it supports the hopper, which has a depending stem c guided in the pedestal b; said recess may be equipped with anti-friction bearings above and below the periphery of the table, and one of these, as the lower one a, may if desired form part of the means for agitating the closures in the hopper and insuring their proper delivery to the ho per chute 2, these details being not fully sliown because they constitute no part of the present invention. Table carries a syrup tank 3 provided with a standpipe 4 by which at 5, subject to the control of a ball-float 6, syrup is supplied to the tank, the standpipe (which rotates with and penetrates table being capped by the stationary delivery fitting 7 of a pipe 8 leading from a suitable source of syrup supply.

Contained in the upper part of the Standpipe is a pipe 9 which forms therewith between them, the syrup passa e and whose bore forms with the bore at tie lower part of the standpipe a passage for the carbonated water, this pipe (which rotates with the standpipe and projects above it) having on its upper end the stationary delivery fitting 10 of a pipe 11 leading from a suitable supply of carbonated water. The fittings and pipes 4 and 9 are suitably packed.

There is provision for nine bottles on the turret 7L at a time. As they are carried around thereby each undergoes filling and sealing. There are nine vertically movable mechanisms which perform these operations, one arranged above each bottle position. They are all alike, and the description of one will therefore serve for all.

In each of nine vertical guideways l2 (Fig. 3) formed in cylinder 7c of the aforesaid rotary upright is movable a main slide 13 which has a roller 14 projecting through an opening 15 (Fig. l) in said cylinder and engaged in the camway 14 of the stationary cam 0. In the Vertical bore 16 of the slide is vertically movable the tubular stem 17 of the sealing head 18 into the upper end of which is screwed the plug portion of a head-piece 19, the parts 17, 18, 19 forming what I term the compensating slide; the slide has a toothed hardened face 20 and the inner end of a block 2l, movable horizontally toward and from said slide and in the head-piece, has a correspondingly toothed hardened face 22, the purpose of which will appear later. The compensating slide has an interior flange 23 against which abuts upwardly an annular closure-applying device 24 of any approved form, the same being supported by an annulus 25 which affords at 25 a closure-supporting ledge and is in turn supported by the rubber gasket 26 which is held against said annulus under a certain amount of pressure, but so as to leave an annular space or chamber 27 therearound, by the mouth-piece 28 screwed onto the sealing head. A plunger 29, formed with a cylin er 30 in its upper end and with a downward protuberance 31 which penetrates flange 23, is normally held pressed against a rubber gasket 32 on said Han e by astron spiral spring 33 interposed ietween sai plunger and the plug of the head-piece 19. Against the lower end of its portion 3l the closure, superimposed on the bottle head, is adapted to bear. Said plunger 29 'has a vertical bore 34 which has held therein, by a nut 35 (Fig. 9), an exteriorly spirally ribbed plug 36 penetrated longitudinally by a port or vent 37. Parallel with this bore it also has a port 38 adapted to connect the space of cylinder 30 with the space of the sealing head below the flange 23. In cylinder 30 is the head 39 of a piston whose stem 13 40 is guided for vertical movement in the head-piece 19 and penetrates block 21, having an inward incline or cam-face 41 adapted, when the piston is raised, to shift the block inwardly to cause its teeth to engage in those 20 of the slide 13. The lower face of the piston head 39 is adapted to abut the top of plug 36 but it has one or more groovelike ports 42 (Fig. 9)whose function will appear. The piston will be depressed when the slide 13 rises by a depresser 43 depending from table 44 is a vent from the interior of the plunger above flange 23 to the atmosphere.

The closure-entrance 45 to the filling-head is formed to deliver a closure, supplied there to from the chute 2 as it passes the same, onto the closure-supporting ledge 25'; but the closure is at first prevented from moving onto the ledge by a pair of convergently arranged stop-pins 46 whose inner ends it abuts, their outer ends forming pistons in cylinders 47 formed in the sealing-head and having vents 48 to the atmosphere and containing light springs 4 9 which tend to urge the vpins inwardly. Around the entrance 45 is formed a channel containing a continuous rubber gasket 50, the face of the scalinghead in which said chamber is formed and the exposed face of the gasket being beveled as shown in Fig. 6. The channel forms behind the gasket a chamber 51 which communicates with chamber 27 by a port 52. Vhen a closure is admitted to the entrance the entrance is to be closed and at a certain point in the operation thereafter the closure is to be pushed positively to its seat onthe closure-supporting ledge. -`For this purpose a gate member 53, U- haped in plan (Fig. 11), is fulcrumed on a pin 54 at the back of the sealing-head, which it straddles; the gate member normally tends to assume the position shownin Fig. 1, but when the sealing-head descends a roller 55 on a depending arm of the gate engages a cam 56 on the part k* and causes the gate to assume the orizontal position shawn bly Fig. 5 so lthat the inner face of its body or outer portion, which is beveled to correspond to the bevel on the sealing-head and gasket 50 (see dotted line 57, Fig. 5), will be face to face with the gasket. Said body portion forms a chamber 58 with an outlet 59 to register with the closure-entrance 45 and with which communicates a cylinder 60 containing a piston 61 which is ivotally connnected to a bent lever or pus er 62 whose free end is adapted to be thrust, on movement of the piston, into or out of the closure-entrance. The piston is moved to cause the inward movement of the pusher by fluid-pressure; opposite movement thereof is caused by a lever 63 which hangs pivotally pendant from the slide 13 and, by its inclined surface 63 wiping against a cam 64 (Fig. 1) in the descent of the slide, is moved against a protruding part of said piston (Figs. 5, 9 and The slide has suitably secured to its side faces the valve chambers 65 and 66 having vertical passages 65 and 66 and valve seat 65 and 66 therein. These valve chambers deliver liquid to the interior of the filling head the former to afford pressure for the performance of certain functions and the latter for the filling of the bottles. Telescoped into the passages of these valve-chambers are the upper ends of pipes 67 and 68 which deliver into the filling head respectively below and above its flange 23, the joint in each case being sealed by a gland 69; a port 67 leads frompipe 67 to the chamber 27 (see Fig. 9). Valves 70 71 are adapted to seat at 65 66, respectively, their stems protruding upwardly through glands 72 and having heads 71 under which take the arms of a two armed lever 73 fulcrumed in slide 13 (Figs..1, 3, 4, 5 and 7). The bore of Valve Achamber 65 is longitudinally channeled. as at 65 down to the valve-seat to permit Huid flow past the valve when it is unseated. Lever 73 has upstanding arms 73 each formed with a shoulder 73 which abats a stud 74 on the head-piece 19 when the sealing-head is fully depressed in the slide; upward movement of the sealing-head in the slide will, by studs 74 wiping past said shoulders, cam back lever 73, raising the valves 70 71 from their seats. In valvechamber 65 is a horizontally arranged port 7 5 (Figs. 7 and 12) which is connected by a port 76 to the bore of said chamber and which contains a valve 77 normally springheld against a seat 75 to close said port; with this port is connected the lower memmer of a telescoped pipe 78 the upper member of which depends from the table w. In valve-chamber 66 are arranged two other horizontally arranged ports 79 80 which are connected by an inclined port 81 (compare Figs. 3, 7 and 10) with the bore of said chamber and which respectively contain valves 82 83 spring-held against seats 7 9 80 to close said ports; with these ports79 80 are respectively connected the lower members of telescopedpipes 84 85 which depend from a syrup-gaging cup 95 to be described, (only 85 communicating, however, with the cup). The stems of all the valves 77 82 83 protrude rearwardly and are suitably packed to prevent leakage. Arranged to be respectively opposite them when said stems have moved down with slide .13 and movable in cylinder 1c are the poppets 86 87 88 which wipe against camways 86 87 88 on cam o. The bore of valve chamber 65 may be put into communication with the atmosphere (to release the pressure above valve 70 for a purpose to appear) through a port 89 adapted to be closed by a valve 90 which is moved to closing position by the oppet 86, through the intermediary of a pllunger 91 and a spring 92, when said poppet is moved to open valve 77 (Figs. 3, 7 and 12).

Water to enter the valve-chambers 66 is conveyed from the pipe 9-4 through a pipe 93 having a T 94 connected with the two telescoped pipes 78 84.

The syrup in the tank 3 is adapted to iow to a gaging cup 95 through a pipe 96 when a normally spring-closed valve 97 is opened through the medium of a lever 98 fulcrumed on the rotating upright and having a roller projecting through an opening 99 (Fig. 4) in said upright and bearing on a camway 91 of cam o. According to the height to which a tube 100 slidable vertically in the top of the cup and open at top and bottom is adjusted the cup is adapted to receive a. cer tain quantity, more or less, of syrup, (valve 97 of course remaining open at least until the syrup thus attains its level in the cup). The cup discharges into telescoped pipe 85, as already stated.

Operation-111e position of the mechanism for the filling and capping of each bottle at the start of the cycle of that operation is shown by Fig. 1, slide 13 being then held by the cam o fully elevated. As it passes the chute 2 a` closure is by any suitable means (not concerned with the present invention) allowed to enter the closure entrance 45 of the filling-head and rest against pins 46 (Fig. 9), the gate being depressed as shown in Fig. l. At o (Fig. 13) camgroove 14 depresses slide 13 and causes plunger 29 to impinge against the bottle head, the filling-head 18 being telescoped over the same, the result of which is the checking ot the descent of the compensating slide sufiiciently to cause pins 74 to rock lever 73 even for the shortest bottle and thus effect both compensating for varying heights of bottles and, by the movement of said lever, the opening of' the valves 70 71. If, as in the filling and consequent increase of pressure within the bottle (as will appear), the bottle should collapse, the compensating slide will fall, allowing the valves to close as soon as the pins 74 clear the shoulders of lever 73. In the position thus assumed by the slide 13 the valves 77 82 83 come into opposition to their poppets 86 87 88 (see Fig. 4). As the main slide 13 descends the gate 53 is closed by its roller wiping over cam 56.

The rotation continuing poppet 86 is actuated by camway 86 to open valve 77, and water under pressure from the T 94 (that is, it may be and in `fact in the present case is charged water from the same source from which the water for filling comes) flows by pipe 67 and port 67 to annular chamber 27 and thence through port 52 to chamber 51 and causes gasket 26 to form a seal around the bottle neck and gasket 50 to press against the gate and form a seal around the closureentranee 45; gasket 32 is already compressed between plunger 29 and flange 23 so that now the interior of the lling-head is sealed ofi' from the atmosphere, except for a certain controlled vent 101 (Figs. 7 and 11) which is to be referred to. The cam 86 holds the valve 77 open for a great part of the cycle (see Fig. 16), so as to maintain the sealed condition of the filling head until, the bottle having been filled, the closure is pressed against the bottle head in the final act of sealing or closing.

Continued rotation brings poppet 88 into position to be actuated by camway 88 and this opens valve 83, permitting the (as will be seen) measured charge of' syrup in cup 95 to flow by gravity via 68 into the bottle; it passes down the spirally ribbed exterior o1 the plug 36 and the air which it (and the charged water, which is to follow) displaces from the bottle passes up through port 37, enters cylinder space 30 via 42, flows down through port 38 to the main space of' the filling-head and thence through opening 59 of t-he gate into its chamber 58, where it acts ultimately to cause piston 6l to exert pressure on the finger 62 which, when the cap is freed, will force it into position over the bottle head.

Further rotation clears poppet 88 from camway 88", so that valve 83 cuts otl the syrup pipe 85, and brings poppet 87 to position to be actuated by cainway 87 and so open valve 82, so that the charged water from T 94 follows the syrup through 68 and down exteriorly of the spirally ribbed plug 3G into the bottle, the air displaced from the bottle continuing to flow into the fillinghead and gate-chamber 58. The air pressure thus stored in the filling head and gatechamber notonly actuates the finger 62, s stated, but it raises the piston 39 and so causes its stem to move block 21 so that the compensating slide is now locked to the main slide as a preliminary to the closureapplying operation. If, on the collapse of a bottle, the compensating slide tends to fall so as to close the valves 70 71, block 21 will offer no resistance because the air-pressure that has been stored up as just explained will then be released, allowing piston 39 to fall by gravity and the block to recede. The air stored as aforesaid I find is more than enough for performing the functions mentioned; wherefore I provide at a suitable point, as at 101, Figs. 5 and 11, a vent controlled by a needle-valve which may be adjusted to allow that leakage which will avoid bottle-breakage without unduly reducing the pressure.

Continued rotation will, at the rise o 1n camway 0, result in a slight upward and downward movement of slide 13, plunger lllfl 29 separating from the bottle head, which is held down by the pressure in the fillinghead, and the closure, being now above the latter and tree to move onto ledge 25', is pushed to a position between the bottle head and plunger by finger 62; the pins are forced back by the closure assisted by the pressure in the filling-head, the air in their cylinders 47 venting'at 48. In the return or downward movement of the slide the plunger presses the-closure against the bottle head,

and since the slide now assumes its lowest level (see 0 in Fig. 13) the sealing device 24 is moved down relatively to the plunger and so aiiixes the closure to the bottle. This results in breaking the seal at gasket 32, so that the pressure stored in the filling-head is vented at 44. As the slide assumes its lowest level lever 63 engages cam 64 and so acts to draw finger 62-out of the closureentrance 45, so that the gate can fall.

Immediately thereafter poppet 86 runs oi camway 86 and not only allows valve 77 t0 re-seat to cut o the liquid pressure that has been holding gasket 26 constricting the bottle neck and gasket 50 pressed against the gate but valve 90 (Fig. 12) to vent valvechamber 65 above valve 70, so that the pressure in chambers 27 and 51 falls and said gaskets retract, releasing the bottle and the ate. g Finally the slide assumes the original level (rising thereto at incline 0, Fig. 13), and

after the amount of the movement allowed for compensating has been taken up and valves --71 are incidentally re-seated the compensating slide rises with it clear o the bottle, the depression of the piston 39--40 being assured by the depresser 43. As the slide rises the gate falls by gravity to the position shown in Fig. 1.

'As soonV as valve 83 is closed by poppet 88 running 0E the camway 88 thecamway 91' causes lever 98 to open valve 97 so that the cup is refilled from the tank 3, camway 91 being shown of a suiiicient extent to allow the cup to be iilled to the extreme height to which tube 100 may be adjusted.

Part 71, on the one hand and slide 13 with slide 17 constitute opposed pressure members between which the bottle or other container is held in such manner'that if the `23 upwardly via the groove part of port 38 and then laterally under and past gasket 32 to said port 44.

As has been pointed out, the valves 70, 71 prevent iiuid flow (even though the valves 77, 83 and 82 are o ened on each cycle) so long as a bottle 1s absent. Of course the principal object is to avoid spilling the liquids on or about the machine, although in the machine in question it also prevents pressure being admitted to chamberv 27 unless a bottle head is present in the gasket to resist such pressure and thereby prevent the gasket from lbeing blown out of itsseat. In the construction shown in Figs. 18 to 21 the contraction of the gasket is effected by iuid pressure the same as before, but such pressure does not depend on presence or absence of a bottle but is admitted on every cycle in any event-which is a matter of omltting the valve 70, while leaving valve 77 to be opened on every cycleV as one rigid structure), 19, 20, 21, 22, 23,

24, 25 (being here integral with 18) 25', 26, 27 and 28, are all substantially the same as before. The closure inlet 45, the gasket 50, the chamber 51 behind the same, port 52 connecting said chamber and chamber 27, and port 67 by which fluid enters chamber 27 from pipe 67 are all also substantially the same as before. The plunger, here designated 102, formed at its upper end with a cylinder 103, has its downward protuberance 104 extended so that when the plunger is fully depressed its lower end obturates and nearly its the hole in gasket 26 and so, on admission of iluid to chamber 27 with no bottle present, prevents collapse or blowing out of the gasket; the plunger has the. vertical bore (105) and therein `the spirally ribbed plug (106) held therein by the nut- (107) and provided with the port or vent (108), and it also has parallel with its bore the port (109) connecting the space or' cylinder 103 with the space of the sealing head below iange 23. The plunger is contained as to its cylindrical part .in a

sleeve 110 whose iiange 110 limits downward movement of the plunger to the exvspacer sleeve 112 interposed between the sleeve and head-piece 19. The spring 113, corresponding to spring 33, here rests on a disk 114 resting on the sleeve 110. The piston, having its head 39 in cylinder 103 and its stem 40 guided in head-piece 19 and rovided with a cam-face 41, coacts with block 21 and is in all respects substantially the same as before, excepting that the area of the piston hea'd is less than that of the protuberance of the plunger. The Syrup and filling liquid enter the plunger 102 from pipe 68 through a projecting nipple 102 thereon (Fig. 21), stem 17, sleeve 110 and slide 13 having suitable slots 17, 110i, and 13 (Figs. 19 and 20) to accommodate said nipple. The operation of the machine modi.

fied as in Figs. 18 to 21 is as lfollows: When the filling head receives a closure on passing the shute 2 said closure comes to rest against the protuberance 104 of plunger 102, which then stands depressed. The main slide then descends, bringing the plunger against the head of the bottle, the plunger being thus held from further descent while the compensating slide continues down and until the plunger abuts disk 114, whereupon the descent of the compensating slide also is Stopped to effect compensation and actuatethe lever 73 for the opening of the valve 71 in the way already clearly explained. The meeting surfaces of the bottle head and plunger are now about coincident with the top plane of closure inlet 45, so that now the bottle prevents inward movement of the closure contained in the inlet. The mechanism now comes around to the positions where valves 77, 83 and 82 are opened in the wa already explained so as, respectively, to a it pressure to chambers 27 and 51 to constrict gasket 26 around the bottle neck and press gasket 50 against the (now elevated) gate 53 and thus enclose the bottle mouth in a sealed space and then admit first the syrup and then the filling liquid, the air driven from the bottle passing up through the bore of plug 106 and then o so to provide the pressure necessary to actuate pusher 62 upon the closure being free to move inward and also acting in chamber 103 to raise piston 39-40, which thus acts, as already explained, to lock the compensating and main slides together. Valves 83 and 82 having closed, the mechanism undergoes the slight rise at o (Fig. 13) to effect separation of plunger 102 from the bottle which will remain seated or held down by the pressure on its support as the plunger is also held up because the area in the now restricted gasket is greater than the area of piston head 39), upon which the pusher wn to said space through port 109' being thereby stopped the appliance 24 is vtelescoped down over the closure and thus affixes it to the bottle head, spring 113 being put under tension so that when the ensuing rise of the main slide occurs the capped bottle' will be ejected from said appliance. The plunger and piston are returned to their lowest limits by depresser 43 when the main slide approaches its highest position the same as already explained. The venting of the pressure stored up in the sealing head of course takes place downward through gasket 26 as soon as, valve 77 having been closed, valve 90 is allowed to open to relieve the pressure in chamber 27, so that gasket 26 (and also gasket 50) retracts inthe way already eX lained.

Having thus fully descri ed my invention, what I claim as new and desire to secure by Letters Patent is:
